摘要:


文题释义:

皮质骨轨迹螺钉:于2009年首次提出,其进钉方向由内下向外上,在矢状位上遵循由尾端至头端路径,在横断面上遵循由内侧向外侧的路径。
上关节突侵犯:是位于邻近小关节1 mm范围内的螺钉和/或螺帽。

背景:皮质骨轨迹螺钉较椎弓根螺钉能有效提高内固定把持力,但其具有学习曲线较长和误置率高的特点,骨科机器人能有效克服上述局限,提高置钉准确性和安全性。
目的:对比机器人辅助和传统徒手置入皮质骨轨迹螺钉在老年骨质疏松性腰椎手术患者中的准确性与安全性。
方法:2015年6月至2021年3月,回顾性分析北京积水潭医院行腰椎皮质骨轨迹螺钉内固定手术的年龄≥65岁骨质疏松症患者。共纳入64例患者,其中机器人组23例采用机器人辅助置入皮质骨轨迹螺钉,共置入92枚皮质骨轨迹螺钉;徒手组41例采用传统徒手置钉,共置入164枚皮质骨轨迹螺钉。使用改良的Gertzbein-Robbins分级方法评估置钉准确性以及头侧小关节侵犯发生率;并观察手术时间、术中出血量、术后住院时间和并发症等。
结果与结论:①机器人组置钉优良率为97.8%,显著高于徒手组的87.2%(P < 0.001);②机器人组和徒手组头侧小关节侵犯率组间差异无显著性意义(P=0.157);③2组术中出血量、术后住院时间以及术后伤口感染率比较差异均无显著性意义;④结果说明,在老年骨质疏松性腰椎手术中,机器人辅助置入皮质骨轨迹螺钉是比传统徒手置钉更准确、安全的方法。

Abstract: BACKGROUND: Compared with pedicle screws, cortical bone trajectory screws can improve the holding force, but they have longer learning curve and high misplacement rate. Orthopedic robots can overcome the above limitations and improve the accuracy and safety of screw placement.  
OBJECTIVE: To compare the accuracy and safety of robot-assisted with those of free-hand cortical bone trajectory screw placement in senile osteoporotic patients with lumbar spinal surgery.
METHODS: From June 2015 to March 2021, data of patients aged ≥65 years old with osteoporosis, who underwent lumbar cortical bone trajectory screw instrumentation in Beijing Jishuitan Hospital, were retrospectively analyzed. A total of 64 patients were included in the study. In the robot group (n=23), 92 TiRobot-assisted cortical bone trajectory screws were implanted. In the free-hand group (n=41), 164 cortical bone trajectory screws were implanted. The modified Gertzbein-Robbins scale was used to assess the accuracy of screw placement and the incidence of proximal facet joint violation. Operative time, intraoperative blood loss, postoperative hospital stay, and complications were observed.  
RESULTS AND CONCLUSION: (1) In the robot group, the proportion of clinically acceptable screws (97.8%) was significantly higher than the 87.2% in the free-hand group (P < 0.001). (2) There was no statistically significant difference in the rate of cephalic facet joint violation between the robot and free-hand groups (P = 0.157). (3) There was no statistically significant difference in the blood loss, postoperative hospital stay, or wound infection between the two groups. (4) These findings indicate that in osteoporotic patients with lumbar spine surgery, robot-assisted placement of cortical bone trajectory screw is more accurate and safe compared with free-hand placement.

Key words: robotic surgery, free hand, cortical bone trajectory, safety, accuracy
